There an infinite number of tower heights that will work. And double that number if you include non grounded towers. Moreover, you can detune the cell tower on purpose.
The main, perhaps only thing is that if there is AM RF currents on the cell tower, it will affect the AM station. So you want no current. Voltage is just fine, actually you are going to have voltage no matter what you do. A quarter wavelength tower can be just fine if floated at the ground end or if it is connected to a stub of the correct length.

It needs engineering and will typically get detuning elements. 100 feet may not even work or perhaps it won't matter, I don't know.

Would there be issues with a cell carrier being to close to an AM site? --
